An Old World monkey, the Wolf’s guenon has been categorized as “one of the most colorful, graceful, and lively monkeys in Africa” (The San Diego Zoo, Mammals: Guenon). This monkey is an African native and has many different names. Most commonly called the Wolf’s guenon, this species of monkeys has also been called Wolf’s Mona monkey and by its scientific name Cercopithecus wolfi. The Wolf’s guenon is typically a medium-sized monkey. The mammal can be 60 inches from head to tail and weigh 6 to 9 pounds, on average (Zoo Atlanta, Wolf’s Guenon). Usually males are larger than females and can weigh up to twice as much. Although usually smaller in size, the female Wolf’s guenon must be physically strong, especially for reproduction. On average, …show more content…
However, it has been studied that when the Wolf’s guenon’s top predator (the eagle) attacks one of the monkeys, the rest of the group flee from the trees and spend more time on the ground. A diurnal species, the Wolf’s guenon is active during the day. The monkeys use this time to forage, explore, and reproduce (The Primata, Wolf’s Monkey (Cercopithecus wolfi)). The Wolf’s guenon is primarily known for its large cheek pouches. The monkeys use these pouches to store food, which can almost hold as much as its stomach can (The San Diego Zoo, Mammals: Guenon).
During its daytime adventures, the Wolf’s guenon rarely explores alone. Usually in troops of twelve or more, the monkeys have to have various ways to communicate to ensure safety and proximity. There are many different calls the monkeys use to communicate. One of the calls is known as a sneeze call. This call resembles the sound of a sneeze and is used to send out a warning alarm to the troop. Another way these monkeys communicate is through staring. When a Wolf’s guenon is staring at another Wolf’s guenon or any other animal, it means that the monkey is trying to display a threatening countenance through intimidation (The Primata, Wolf’s Monkey (Cercopithecus wolfi)). The Wolf’s guenon’s behavior is very interesting in the topic of reproduction. Within the troops of twelve, there is usually one male and
As part of the only Old World Monkey group I analyzed the Silver Langur whose scientific name is Trachypitneus Cristatus. In this cage there was a total of 6 monkeys so there was very much activity. This
Primates are one of the most interesting mammals on earth, not only because of their complex social structures, but because they hold so many similar characteristics to humans. Primates are often cited as our closest living relatives and on two separate occasions I observed four separate species of primates at the San Diego Zoo that can justify their use of their physical characteristics and behaviors that may be similar as well as different to the other primates and ours.
As the animal rights movement has developed and grown substantially in recent years, there has been an increased focused on the welfare of captive animals. A popular institution that has received much attention for keeping animals captive is the zoo. Because of this focus, zoos have responded by publicizing their positive benefits for existence in order to justify keeping these animals on display. Since the term “zoo” can have a wide variety of meaning and characteristics, it is important to define what constitutes a zoo in this essay. Zoos are defined as a facility in which animals are confined within enclosures, displayed to the public, and
An observational study conducted, concluded that wild capuchins use anvils and stone pounding tools as a means to facilitate nut-cracking . In the study, a group of ten wild capuchin monkeys where observed in a habitat that is scarce in food, aside from palms. There are different types of palm nuts, larger ones with an oval shape and smaller ones that are as small as 2.5 to 3 cm in diameter. It is interesting to note that many different anvil sites were observed, and what is more interesting is that on the anvil sites, river pebbles were seen and since these are not usually found in the area, it can be assumed that capuchins transport their stones to the anvil sites. An abundance of palms, yet otherwise limited food, has contributed to tool use for nut-cracking becoming a common routine. As a result of the study, wild capuchins were directly observed using anvils as tools for stone pounding. Additionally, characteristic depressions on anvils as well as palm shells and stone pounding tools leftovers indicate nut-cracking. Capuchin monkey choose anvil sites that provide a flat surface to facilitate nut-cracking, often the anvils used by capuchins are made of sandstone or siltstone, but they can also be boulders and fallen trees Essentially anything in the capuchin’s vicinity, that could provide a suitable substrate. When capuchins crack palm nuts, they typically hold the selected stone using both hands and stand in a bipedal
Zoos present a certain blend of nature and culture. They have always provided a way to bring natural wildlife and urban Americans together as a means of entertainment. Yet, throughout the years the role of zoos have changed. Though once used for amusement, zoos are now being used for education on preservation and the welfare of endangered species. One may wonder where and how the idea of zoos started and just how they, and the environment around them, have changed throughout history.
Isbell and Wright’s articles both focus on monkey species and their native environments, Africa for Isbell’s (1994) vervet Old World monkey and South America, Peru area, for Wright’s (1994) owl and titis monkeys. The articles main focus is the relationship between these monkeys and their natural predators. Focusing on how the predator aspect of their lives is determined by their environment and adaptations they make to ensure survival. Isbell’s Vervets Year of Doom focuses more on the adaptations that was forced upon the vervets’ because of their changing environment, the death of fever trees. While Wright’s Night Watch on the Amazon focusses more on how the primates way of life affects their relationship with predators and the likelihood of attacks. Both articles have similar aspects however the species way of life, specifically their environment and sleep schedule, are quite different as well as the authors way of observing and studying the primates within their habitats.
The hands are hook-like, with four elongated, curved, fingers.” (The author) then goes on to describe how the thumb of the brown spider monkey is “reduced,” which is helps in swinging and gripping branches while the monkey travels in the upper canopy of the rainforest. The coloration of brown spider monkeys ranges from light to dark brown on the upper parts of their body and their head, while the inside of the arms and legs is a slightly lighter color of brown. Some individuals of the brown spider monkey population also possess the conspicuous characteristic of a white triangular forehead patch. Behaviorally, the brown spider monkey is a diurnal and very social species. They live in what are known as “fission-fusion” societies in which smaller groups, up to about 30 members, are formed during the day. Male spider monkeys usually travel in all male groups while females travel with other females and their offspring, though it is not necessarily unusual to find a brown spider monkey traveling or foraging alone. At night, brown spider monkeys sleep in trees in the high canopy away from most predators. They choose a location to sleep that is near a fruit tree so they do not have to travel far the next day to find food. Differences in sizes of these groups occur due to varying availability of fruit. When fruit is abundant, the groups tend to be larger and when the amount of fruit is limited they
The observations of Common Squirrel Monkey (Saimiri sciureus) and Western Gorillas (Gorilla Gorillas) were made on 31th October, 2015 at the San Francisco Zoo where is located on 1 Zoo Road San Francisco, CA 9413. The observations has lasted about 3 hours, from 1:40 pm – 4:40 pm, and each primate has been observing for around 1 to 2 hours. Common Squirrel monkey is a small new
The gray wolf is one of the world’s most well known and well researched animals with more documentation on them than any other wildlife species. It is a canid whose main habitats are in the wilderness of remote areas in North America, Eurasia and North Africa. It is the largest member of the wolf family, usually weighing between 70 and 120 lbs, and closely resembles in general appearance and proportions to a modern day breed of dog known as the German Sheppard, although they typically have a larger head, narrower chest, longer legs, straighter tails and bigger paws. The narrow chest of the gray wolf allows for swift and efficient movement through the common elements of their environment such as snow, brush and other conditions. Their larger heads indicate their higher level of intelligence and their large paws, webbed with fur aid in movement across mud and snow. The colour of a gray wolf’s fur lives up to its name and is predominantly a mottled gray although the gray wolf can also have fur that is nearly pure white, mixes of red, brown, or black. Being very social animals, gray wolves do mostly everything in packs of 2 – 15 animals; living, traveling and hunting. They can hunt and feed off smaller game, yet with their large pack size, they can work collectively to bring down large game such as deer, moose or bison. There are 37 recognized subspecies of the gray wolf in total ranging across six continents with familiar names that one
Long before the settlers started to make the United States their home, “American Indians lived long beside the Gray Wolf before settlers started to come here.” (Rowe, Mark) The wolf is native to the North American continent and has been inhabiting its land for centuries. It is a canid species, or member of the canine family and is a cunning, smart, fast, and sly animal. Gray wolves range in color from black, brown, gray, and white and also look like a grown German Shepherd. They are well known for traveling in family sizes from 7-9 wolves, led by the alpha male and have a mate. They are a fierce animal that has been researched extensively because of their unique qualities and that they are near extinction.
On Friday, March 31, a observation study was conducted at the L.A. Zoo. The time of arrival for the observation was at 11:48 am and the end of the observation was at 2:42 pm. The weather condition at the zoo was very sunny with a mild gust of wind every so often, which is a perfect weather condition to conduct a study. The main reason for conducting this observation study was to study and gather information about the many different types of primate that are located at the zoo. To see how different or similar each primate is to one anotherin different aspects.
In the end, the Golden – Cheeked Gibbon is a fascinating primate that has a unique style of motion and call. While I did not experience that call that the gibbon uses to either have a mating partner or claim its own territory, it does exist. Their way of moving throughout the enclosure is fascinating to watch as they swing their long arms around. Moving from prop to prop they are easily able to move from one side of the enclosure in under ten seconds. The primates provided key examples on similarities that humans share with these animals, and other primates. The interaction
Arctic Wolf aka (polar wolf or white wolf ) Melville island wolves live where few other animals can survive. They have a very unique color due to the location that they live in. There weight depends on where they live some weigh upto 75 pounds other weigh 125 pounds. Some of them are about 3 feet in length but some can be up to 6 feet up in length.They have two thick layer of fur.The outer layer actually gets as winter months come along.The first layer helps to form a waterproof barrier for the sun. There body temperature can stay warm enough even when it is bitter cold . There also have smaller ears than other wolves and their paws are patted so it easer from them to walk on the bitter cold ground. Its believed by most that they evolved
Addressing the various mating systems of primates and its relation to sexual size dimorphism and behavior contributes to understanding evolutionary processes and patterns. The different methods of mating are significant to study because they demonstrate the outcomes of natural selection on mate choice. These varying mating methods also aide in understanding the origin of
The main aim of zoos is to protect and conserve global biodiversity and wildlife. To do this they have four roles to play which are; research, conservation, education and welfare.
